' To all lwhom it may concern.'

7 Be, it known that I, WALTER L. FRY, a

citizen of the UnitedStates, a resident of.

the City. of Detrdit, county o 1,Wayne,-and State of Michigan, have'iiinvented an Im- :provernent in Antirattlers, pf which the foladapted for use in eonne'ctionwiththe doors 1G or windows or other hinged or removable iportio'ns of vehicle bodies, and particularly lit to automobile'bodies. In automobile bodies,

fthe hinged or removable portions are particularly likely to become loosened and to rattle by reason of the severe jolting the body receives due to the movement of the vehicle, and by reason of the movement of the parts .of the body with respect to one another incident to the twisting stresses applied to the frame upon which the body is mounted, and to other causes.

Some of the objects of my invention are to properly locate or position the anti-rattlers upon the hinged door or window or other movable member of a body, so that they may exert their action in the most effective manner and to provide an anti-rattler` of simple constructiornwherein the buer element is completely protected against abrasion. My invention also aims to provide a suitable buffer for the corner of a door or window, which will act upon two edges of the door or window in the plane of the door or upon two edges of the door and window, and in addition thereto, upony the inside of the door at right angles to the plane of the door. Other objects of my invention will be pointed out in the following specification.

u I have discovered that anti-rattling means, in order to be most effective should be so constructed and arranged as to exert their action in the plane of the door, although such anti-rattling means may be supplemented by anti-rattlers exerting their action in a direction perpendicul ir to the plane of the. door. I have also found that the antirattlers which exert their pressure in the plane of the door should be placed at certain positions in order to most effectively cushion the shocks. Itwill be understood, however, that my improved anti-rattler is not limited to use in any particular place,

and that it may be applied in other places if desired.

In the drawings, Figure l'is a side view of an automobile door indicating the positions at which the anti-rattlers should be placed; Fig. 2 is a sectional view of a form of my improved anti-rattler particularly adapted for use at the corner of the door; Fig. 3 is an end view of the anti-rattler shown in Fig. 2, partly broken away in order to show the position of the parts; Fig. 4 is a perspective view of another modification of my invention and Fig. 5 is a sectional view of the modification shown 1n Fig. 2l.

Fig. l may be taken to represent either a full door, including a window frame such as is used in a brougham or limousine, or a half door, such as is used on the ordinary touring car. If the drawing is taken to represent the latter, portions lying above the line lie-B may be disregarde Considering Fig. l to represent the half door, and disregarding such portions of the drawing as lie above the line .Li-B, l represents the door which is hinged at one ed e by means of the hinges 2-2 The positions of the anti-rattlers are indicated at 3, 4 and 5. The anti-rattler 3 is placedvupon a door member so 'as to act upon the unhinged edge lof the door at a point adjacent to its upper edge G, and in the plane thereof. Anti-rattler f-L is placed upon a door member'I so as to act upon the unhingcd edge of the door at va point adjacent its bottoni. Anti-rattler 5 is placed upon a door member so as to exert its action upon the botte-ni A edge of the door in the plane thereof, at a point adjacent the unhi ged edge.

It Awill be obvious that the anti-rattlers may be placed upon the door post, door sill, door rail, door stile or the door stop, and I therefore do not wish to limit myself to placing said anti-rattlers upon any one of said door members.

If desired, anti-rattlers 4i and 5 may be combined in a unitary construction, such as is illustrated in Figs. 2, 3, i and 5.

Considering Fig. l as a drawing of a full door, such. as is used in limousines and the like, the points of application of the antirattlers are shown at 3', 4, 5 and 5. In such a constructionv the door is hinged by means voccupies 5 comes loosened,

of hinges 2, 2 and 2", and anti-rattlers t and 5 occupy the saine positions as they would inthe case of a halt' door. Antiwattler 3, however, is omitted or moved to position 3, that being so as to act upon the unhinged edge of th-evdoor in the plane thereof, ad jacent to its upper edge. Antimattler 5 a position corresponding to antirattler 5, acting uponthe upper edge of the door in the plane thereof and adjacent to i the unhinged edge.

- I have found that the points at which the anti-rattlers are `placed according to my invention, are the points or first impact for the various conditions of looseness ot' the door from which rattling proceeds. Thus, considering Fig.` 1 as a half door and disregardin the portions of the drawing` lying above thelineA-Jl, it will be seen that if the upper hinge loosens,fthe door will fall away to the left at the top and will iirst strike the door post at-or about the point On the other hand, if the lower hinge he- Athe door may' fly upward and thus lrst strike the post at or about the point 4. It' the whole door be loosened and sag orif the upper hinge become loosened and there is sutlicient clearance between the door and the door post, the door will lrst strike at or about the point 5.

Considering the drawing as an illustration of a t'ull door, it will be seen that it the upper hinge or hinges loosen, the door will first strike at or about the point of 3. lf the lower hinge-or hinges loosen, the door may ily upward and strike at or about the point 4. It the whole door be moved bodily downward, due to loosness of thc hinges, the door will lirst strike at or about the point 5 or if it be inoved upward, atyor about the point 5.

I thus provide anti--rattlers at first impact instead of at points removed thercron'i, as is the present practice, and it will be noted that 1 make no at* tempt whatever to hold the door in position y means of the anti--rattlers, .but permit the door Ito make such movements as it will, under the conditions of operations. Any attempt to hold the door in positionjsimply re` sults inthe loosening of the hinges and consequently an aggravating of the conditions producing rattling, permitted to move, the eflort being simply to absorb the shock incident to such movement, the door will always remain hung from the hinges and the hinges will consequently remain tight for a longer time.

rMy improved anti-rattler consists primarily of two members, one of which, the buffer member, is made of resilient material and the other of which is made ot' metal or other suitable material adapted to resist points ol3 somewhat In Fig. 2 l have illustrated a forni oi" iny whereas, ii thedoor be' Leagues 4 invention applicable to the corner of a door 'and Adesigned to absorb shocks occurring at an angle to one another and in the plane of the door. Such a construction may be conveniently used at the points 4`5 'of Fig. l. The embodiment show in Fig. 2 oonsists of the buii'er member T recess formed at the corner which buffer member is supplied with a pair of wear plates la4 and 15 located at an angle of one another. Bearing upon the wear plates are a4 pair of plungers- 16 and* 17 which are connected by a metallic shoe 18. In this modification, ifI pressure is produced at the point 4, the plunger V16`willmove'inwardly, thus depressing'` wear plate 14 and compressing buffer 7. PlungerqlV duringI this time, will slide longitudinally of the wear plate 15, such movement .being iuitted by the slot in thecasting 19. On the other hand, if pressure is` produced atthe point 5, plunger 17 willmove in'wardlythus compressing buffer 7 and causing plunger- 16 to move alongnyvveaif plate 14 through the slot provided for `this purpose. Both actions, however, may occur at the'same -pertime,

and both plungers may be, to a slight extent,-

simultaneously moved along their wear plates, and caused to bring pressure to hear upon the butler 7, The entire anti,- rattler may be conveniently attached to the'v corner of the door by ineans of screws 20 or' lrespective in any other suitablel manner.

In Figs. 4 and 5 I halve shown a modication of my invention corner of `thedoor when` exert an action both in the and in a? plane vat right modification provides for the cushioning of shoelts at the pointsl'and 5 of shocks'oc curi-ing between the-inside of the door and the door stop. member whch may be conveniently formed in the shape of a cube set into the lower inside cornerof the door at itsnunhinged edge,` and a protective plate 21, vwhich surrounds the corner of 'the door on three sides. Protective plate 21 may be held any suitable' means, 'such attaching' it to the rubber Abilder 7 and fastening the latter in position, or by'means fastened to the door rail and passing through a. hole 23 in the Yproteating plate. Hole 23 is made large enough s o that movement of the plate 2l rattler isin the inoperative rests against the edge of the hole 23. es shown in Fig. 5, the underside of plate 21 is slightly beveled to ride up upon the door sill. 8 and when the door is closed, the ant"- rattler will not door sill 8 but A and the door post"(i1ot shown).
